Rennin present in the gastric juice of infants digests

Correct option is B

Correct Answer: B. Proteins

Explanation:

• Rennin (also known as chymosin) is an enzyme found in the gastric juice of infants that specifically helps in the digestion of milk proteins, particularly casein.

Information Booster:

• Rennin converts soluble casein (milk protein) into insoluble paracasein, making it easier for pepsin to further digest it. This is crucial for infants who rely heavily on milk.

Additional Information:

• A. Carbohydrates

  • Digested by enzymes like amylase, not rennin.

• C. Fats

  • Broken down by lipase enzymes.

• D. Nucleic acids

  • Digested by enzymes such as nucleases.
